Abstract

L'invention concerne un dispositif à magnétorésistance qui présente une structure du type réseau artificiel ou « spin valve », un rapport MR élevé avec une quantité d'oxygène aussi faible que possible dans une structure multicouche, et une excellente stabilité thermique. Le dispositif à magnétorésistance comporte une structure dans laquelle les couches non magnétiques et les couches ferromagnétiques sont formées sur une base ; ou les couches non magnétiques et les couches ferromagnétiques alternées sont formées sur une base, et une couche non ferromagnétique est formée sur la couche ferromagnétique la plus élevée. Le dispositif est caractérisé en ce qu'un élément tampon est prévu sur la surface, côté base, de la couche ferromagnétique la plus proche de la base ; cet élément est constitué d'au moins un premier élément sélectionné dans le groupe comprenant Si, B, C et Ge, et d'au moins un deuxième élément sélectionné dans le groupe comprenant Fe, Ti, Cr, Mn, Co, Ni, Cu, Zr, Hf et Ta.
